There has not been seismic data available recently for technical reasons, but a weak thermal anomaly remains visible on satellite data and suggests ongoing occasional explosive (strombolian) activity. [more]

Seismic and external activity have been weak recently. No significant explosions were reocrded in the past days. [more]
Karymsky volcanoKarymsky is the most active volcano of Kamchatka's eastern volcanic zone and a perfect symmetrical stratovolcano. Ash eruptions from Karymski can come in the way of aircraft flight routes across the N Pacific. Karymsky, the most active volcano of Kamchatka's eastern volcanic zone in one of the world's volcanoes with persistent activity and has been erupting for at least about 500 years.
Background:Much of the cone is surrounded by lava flows no older than 200 years. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.
The cone has been constructed during the past 2000 years within a 5-km-wide caldera that formed about 9,000 year ago within a complex system of overlapping calderas. The caldera cuts the south side of the older Dvor volcano and is located outside the north margin of a large, still older caldera (the mid-Pleistocene Polovinka caldera), which contains the smaller Akademia Nauk and Odnoboky calderas.
Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, which is located immediately south of Karymsky volcano.
